Always go heaver than you think you need with toroid xfmrs.Remember
they dont have a iron core which helps to stabilize surges
(reluctance).A toriod coil (air core) can delever masive amounts of
power for a very short time,but long enough to fry electronics. The
big thing is regardles of how much power you have avalable they make
fuses in all shapes and sizes.USE ONE FOR EA DRIVE.
